Reject dirty data! Don’t let it in, no matter what happens

More of a note to myself. Just working on the JSF bindings of the soon to be announced openEHR framework, and due to nature of my persistence model, once bad data finds its way into db, it messes the whole form entry. It is possible to modify the persistence mechanism for immunity to bad data, but is that something I should do? I guess not.

When bad data appears in the system, it should stop the execution. You (I) should find why that happens, and fix it. I’ll keep the persistence a little bit fragile intentionally. Better to discover potential problems now, then trying to find them in production system.
